heat prostration[edit]

typing 'prostration' leads to the article about prostration, however at the top it says, "For the medical condition of heat prostration, see hyperthermia." This article does not use the wording 'prostration'. This may lead to some confusion when someone is looking for 'heat prostration'. -- (talk) 15:18, 28 March 2010 (UTC)

Hyperthermia in animals[edit]

This article presumes that this is a medical condition of humans. Wouldn't the same term be used to describe the condition - but with different critical temperatures in other animals? Rmhermen 14:59, Apr 1, 2005 (UTC)

Delete the "heat exhaustion" link at the bottom of the page? Because of the re-direct, it currently leads directly back to this page again. The preceding unsigned comment was added by (talk • contribs) 21:55, 1 June 2005.


I suffered some sort of heat exhaustion while abroad in Egypt this summer. Ever since, I can hardly handle sun anymore without becoming naseaus and dizzy. I'm 21 and live in California, so this is really scaring me. Is there any information on the after-effects of hyperthermia?

Please go see a doctor. 18:55, 20 July 2007 (UTC)

calenture is also the name of a Finnish rock band [disambiguation}[edit]

My apologies for not knowing the proper etiquette for offering comments on Wikipedia entries. I am a newcomer but an enthusiastic one. I have seen these "disambiguation" pages, and I thought that these comments might belong to such a page: (1) "Calenture" happens to be the name of a Finnish rock band: (2) "Calenture" is also a term used on the 3rd page of a comic fantasy novel called "Going Postal" by Terry Pratchett. signed: S.J. Codd [ Huntington Beach, California -- January 19th, 2006 ]

Hi SJ. As (2) is just a term, it would go in Wiktionary rather than Wikipedia. As there is currently no Wikipedia article for the rock band, there is currently no need for a disambiguation page. Disambiguation pages are not needed for every occurrence of a word in the English language - only where there are 2 or more Wikipedia articles. Nurg 11:01, 27 February 2006 (UTC)

Calenture also happens to be an important 1987 album from little-known Australian rock band The Triffids, no doubt the band named themselves after it. But does the redirect here mean we should assume it is a synonym for hyperthermia? Because that album has an uncredited dictionary entry on the cover:

CALENTURE. [phonetics omitted] Tropical fever or delirium suffered by sailors after long periods away from land, who imagine the seas to be green fields and desire to leap into them.

If they are not synonyms but just related concepts, this article should explain how. JöG 22:37, 21 February 2007 (UTC)

Heat exhaustion[edit]

What are the symptoms and characteristics of heat exhaustion or heat prostration? Nurg 11:05, 27 February 2006 (UTC) in this early stage of heat illness, one has confusion, cramps, and nausea but is still able to sweat. when it goes to heat "stroke", you can't sweat so your temp shoots way up and you go on to seizures, organ failure, and often death.Sfahey 17:28, 28 February 2006 (UTC)

eMedicine Specialties > Emergency Medicine > ENVIRONMENTAL (Heat Exhaustion and Heatstroke) states that 50% of people presenting with heat stroke are still sweating ... says loss of sweating is a late stage development. Characterises heat stroke as >40 degrees and central nervous system dysfunction. —Preceding unsigned comment added by (talk) 05:46, 21 July 2008 (UTC)

Both 'heat exhaustion' and 'heat prostration' redirect here. However, I feel this condition is not adequately covered by this article. Suggest that either this article be expanded to cover that condition, or it gets it's own seperate page?shockeroo 10 June 2006

I agree. These are lesser degrees of hyperthermia, and should be dealt with here. Sfahey 19:04, 11 June 2006 (UTC)
I would also support splitting that content out into its own article. --Arcadian 19:48, 11 June 2006 (UTC)
I added material on these topics, including that they are on a spectrum with heat stroke, with all being types of hyperthermia. Sfahey 13:20, 12 June 2006 (UTC)

Thanks to this article...I think I just saved myself from a very miserable evening. Wikipedia rocks for all your first aid needs (lets just hope you can crawl your way to the computer and do some typing like I had to). A wet towel to special areas == feeling MUCH better quickly. I know this is lame, but I seriously felt like I was dying or something 20 mins ago, and now I'm doing alright, so thanks to everyone who contributed to this article. --User:Bdiddy

Wikipedia (or the internet as a whole, with rare exception) should ABSOLUTELY NEVER be used as a first aid or health reference. Poor information with most other situations will, at worst, get you an F or make you look silly at a cocktail party. Where health is concerned, poor information could make your illness much worse. - 02:30, 2 August 2006 (UTC)

Heat Exhaustion Part II[edit]

If heat exhaustion is a separate thing, as the article claims, why does a wiki link lead back to this article? (Narkstraws 19:44, 5 August 2006 (UTC))

Heat exhaustion and heat stroke are two stages of "Hyperthermia." In the same way that "Fracture" might include discussion of "open fracture" and "closed fracture," that's how it was/is done here. Sfahey 02:00, 8 August 2006 (UTC)

Revert due to possible copyvio[edit]

Just in case you were wondering why I did the revert. Whole paragraphs were taken from the following site: [1]. If you feel that it my revert was unjustified, feel free to revert it back. Thanks! zephyr2k 15:52, 19 September 2006 (UTC)


"Victims may become confused, may become hostile, often experience headache, and may seem drunk."

Is "victim" a proper word in this case?

Sweating is Endothermic?[edit]

This article lists water evaporation as being endothermic, and therefore a coolant for the body. Endothermic reactions GATHER heat from the surroundings to the reacting body or chemical. I believe the opposite word is intended; that the mechanism is exothermic; radiating heat, thus cooling the body? Compare highly exothermic substances such as thermite. Falkvinge 05:11, 3 January 2007 (UTC)

  • Commented later: I just realized that the intended meaning is that water evaporation itself is endothermic, drawing heat from the body and thus cooling it. However, in the context, I first read "endothermic" as applying to the body and not the water evaporation - implying that sweating draws heat from the surroundings to the body. I will try a rewording and/or clarification. Falkvinge 05:15, 3 January 2007 (UTC)

Unclear descriptions.[edit]

"Immersing a victim into a bathtub of cold water (immersion method) is a recognized method of cooling. This method requires the effort of 4-5 persons and the victim should be monitored carefully during the treatment process." Why are 4-5 people necessary? 06:48, 24 January 2007 (UTC)

Presumably to safely carry the person to a bath. Ever tried man-handling someone into a bath without bashing their head on anything? Can't be easy. GoldenRing 02:34, 30 March 2007 (UTC)
I think it more likely that the author was referring to the fact that it is exceedingly difficult to hold a person in a cold bath, especially if that person is an adult male in reasonably good health. Because hyperthermia severely restricts judgement, that person, if even marginally aware of his/her surroundings, is going to vigorously resist when plunged into cold or icy water. Primium mobile 16:26, 18 May 2007 (UTC)


Would it be helpful to have a section on this page on the etymology of hypothermia and hyperthermia? The words are derived from the Greek hupo and huper meaning under and over, respectively. GoldenRing 02:47, 30 March 2007 (UTC)

What are the numbers on the upper right hand corner?[edit]

I notice a table of numbers and cryptic names on the upper right hand corner. Can anyone please put in a paragraph in the article of what they are and what they mean? It seems a bit too cryptic for an encyclopedia??? I hope I am not too unreasonable?? Allyn 15:32, 30 May 2007 (UTC)

Removed Hyperpyrexia[edit]

Hyperthermia and hyperpyrexia are two different animals, however simlar, both are not the same. As such, I've rmmed it from the article. Regards, Navou banter 17:04, 29 August 2007 (UTC)

Is there a reliable source to support this contention? Scray (talk) 16:05, 6 September 2008 (UTC)
I'm going to propose merger of hyperpyrexia and hyperthermia, because they are not distinct. I'll direct discussion here. Scray (talk) 16:08, 6 September 2008 (UTC).
Agree that it should be merged. Copy my posts in the new section Kensplanet (talk) 16:13, 6 September 2008 (UTC)

Actually they are different. Hyperthermia is when the body's temperature is too high over what it's supposed to be from an outside source like what could happen from being outside in extreme heat. Hyperpyrexia is when the body believes the normal body temperature is supposed to be higher and raises it to that. If you have a fever, that's the body raising it's internal set temperature to above what it normally is, but fevers don't usually get to the point of getting that serious. This is how I understand it from the articles anyway, I didn't read it from somewhere else. So think the main differences are the cause and treatment. Hyperthermia is an external problem causing it and hyperpyrexia is an internal problem causing it. (talk) 13:37, 21 September 2008 (UTC)

I agree that the articles make this distinction, but they provide no reliable source, and if no one does soon then I think they should be merged. I would argue that we should not preserve the distinction, and consider them synonyms, if no reliable source is provided. I have always had the impression that they are synonyms - and the inherent meaning of the words seems to support this. --Scray (talk) 19:53, 21 September 2008 (UTC)

Extended Exposure[edit]

Is there any data on the effects of heightened core body temperature over a period of time, such as having a mild fever for a week or more? (talk) 01:23, 25 April 2008 (UTC)

Merging with hyperpyrexia[edit]

Merging hyperpyrexia into this article wouldn't really be wise due to the fact that the two are quite distinct from one another medically. I am afraid that if they were merged and hyperpyrexia was re-directed to this page, then people would assume they are synonymous. If they were to be merged, it would have to be done carefully with a proper explanation that they are two different medical conditions. Uvadaniel (talk) 02:14, 14 February 2009 (UTC)

Please provide a reliable source that clearly makes this distinction between hyperthermia and hyperpyrexia. --Scray (talk) 02:22, 14 February 2009 (UTC)

I'm really just going off of usage by myself and my colleagues. They have different ICD-10 codes. Is the fact that the WHO considers them distinct not sufficient?Uvadaniel (talk) 02:47, 19 February 2009 (UTC)

I've found a source. Harrison's Principles of Internal Medicine, 17th Edition. Chapter 17 explains the differences between fever and hyperthermia as "Fever is an elevation of body temperature that exceeds the normal daily variation and occurs in conjunction with an increase in the hypothalamic set point" and "Hyperthermia is characterized by an uncontrolled increase in body temperature that exceeds the body's ability to lose heat. The setting of the hypothalamic thermoregulatory center is unchanged." It goes on to state "A fever of >41.5°C (>106.7°F) is called hyperpyrexia".

If anything, I would merge hyperpyrexia with fever, since it is a specific stage of fever (above 41.5°C). Uvadaniel (talk) 02:59, 19 February 2009 (UTC)

I agree. Thanks for being so clear. --Scray (talk) 03:45, 19 February 2009 (UTC)

The Graph[edit]

The graph sucks. what do the 2 bars mean??? —Preceding unsigned comment added by (talk) 19:24, 22 June 2009 (UTC)

It certainly isn't intuitive. I've added the caption for the same figure from Fever, but I hope we can improve on the graph. It looks like original research, specifically synthesis, to me. --Scray (talk) 22:17, 22 June 2009 (UTC)

Expert needed[edit]

Heat stroke and hyperthermia are not the same thing. Hyperthermia is a symptom well heat stroke is a disease definition. Will try to correct this area at some point in time.Doc James (talk · contribs · email) 16:57, 9 September 2009 (UTC)

Thats' a surprise, having had First Aid, and Fitness leader training they tend to imply otherwise. Hyperthermia is the symptom that leads to the occurence of the disease (or 'condition'?) of heat stroke. Is that more correct? -- (talk) 04:48, 23 December 2009 (UTC)
I think that different sources use the terms differently -- sometimes as synonyms, sometimes as severity levels, sometimes to differentiate between the medical sign (technically, not a symptom, I guess) and the disease. WhatamIdoing (talk) 05:11, 23 December 2009 (UTC)
Thanks for comment. As I recall it went, Dehydration, leads to, heat stress, Hyperthermia, then Heat Stroke. This is from health & fitness Rehydration information and First aid books, which may be out of date by now. (3 years since my last First aid course.-- (talk) 06:27, 23 December 2009 (UTC)
If you look at a medical text like say Rosen's Emergency Medicine. It does not present it like this. Hyperthermia can be a number of disease with a very high temperature. Dehydration is a low intravascular volumn. Heat stress and heat stroke are specific head related disease.Doc James (talk · contribs · email) 15:51, 23 December 2009 (UTC)

Prevention & Mitigation[edit]

This section has 2 in-text links to the one company I will investigate a little, but if any editor thinks these should be removed immediately due to Wiki guidelines, go ahead.

  • Just after "vehicle-powered cooling system" there is an extra space that I can't remove ??
  • Needs to have Celcius temps added to Fahrenheit.

Minor, yet confusing mistake[edit]

37.7 °C (99.9 °F) 37.5–38.3 °C (100–101 °F) are both in this article, obviously this is impossible, so could someone review my thoughs and correct the article. 1-37.7c=99.9f (assuming this, I don't know) 2-37.5c=100f 3-a function that transforms *C to *F always has a positive slope (easily verifiable through wolfram alpha) 4- one of the above three has to be wrong. (talk) 00:27, 8 December 2011 (UTC)

Temperature set-point[edit]

I've reluctantly added a small section on temperature set-point. This concept is referred to at various points in the article, but the internal links provided don't actually say much about it. Initially, I tried searching Wikipedia for better internal links but couldn't find any. In the long run, it was easier to write a short section. Comments and suggestions or improvements welcomed.--Mdscottis (talk) 22:45, 13 January 2013 (UTC)

Discussion of hyperthermia as medical therapy needed[edit]

Hyperthermia is sometimes used as a medical treatment, e.g. in cancer therapy, but this article neither discusses that nor points to any other article that does discuss that. Bhami (talk) 04:35, 18 April 2014 (UTC)

Hyperthermia therapy is a separate article. WhatamIdoing (talk) 06:35, 10 October 2015 (UTC)

The hyperthermia looks like the fever[edit]

The hyperthermia looks like the fever because both increase the body temperature. --Vinci2005 (talk) 11:34, 29 April 2016 (UTC)
